CHARLES H. GIBBS, OF BUFFALO, NEW YORK.'

HEATING-STOVE GRATE.

SPECIFICATION forming part of Letters Patent No. 227,242, dated May 4,1880.

Application filed February 19, 1880.

To all whom it may concern:

' Be it known that I, CHARLES H. GIBBs, a citizen of the United States,residing at But'- falo, Erie county, State of New York, have inventednew and useful Improvements in Heating-Stove Grates, ot which thelfollowing is specification.

This invention relates to certain improvements in that class ofstove-grates which are constructed with a cone-shaped dumping-sectionarranged within a surrounding annulus or ring.

My invention consists of an oscillating central conical grate-sectionformed with a laterally projecting operating handle and lugs which setin recesses in a surrounding' conical annulus or outer section, saidouter section rest-ing at opposite side edges upon bifurcated bracketsformed on the upper side of a permanently-fixed cross-bar, all of whichwill be more fully hereinafter described in detail.

In the accompanying` drawings, Figure l represents a perspective view ofa grate constructed according to myinvention. Fig. 2 is a longitudinalvertical central section through the grate and the supporting cross-bar.Fig. 3 represents a perspective view of a portion ot' the lower sectionofthe grate, showing one of the recesses for the lugs on the uppersection; and Fig. 4L, a perspective view of a portion of the uppersection, showing one ot' the lugs for supporting the saine.

Referring to the drawings, it will be seen that my improved grate iscomposed of two conical sections, the upper section, M' of which isdetachably connected with the lower section, m, and arranged within thesame so that it can be readily tilted for the purpose 0f dumping thegrate. The apex of the section M' extends upward within the lowerportion of the fire-pot, and the lower edge of said section is providedwith two opposite radiallyprojecting lugs, m', rounded on their lundersides, which rest in corresponding receivers or seats in the lower andouter section, m, and said grate-section M' is also provided with ashaking-handle, N, which curves outward under the outer section, m, andis provided with a suitable socket for a shaking-wrench. The outersection, m, ofthe grate rests directly upon the tips et' theupwardly-projecting prongs of bifurcated brackets O, secured near theopposite ends ot' a permanent cross-bar, P, the ends of which arebeveled, as at p, and are adapted to be secured to acorrespondinglybeveled seat in an ordinary stove. 'Io pointsdiametrically opposite each other a cross-bar, R, is securedto the underside of the outer section, m, and this cross-bar has atits center adownwardly-projecting journal, r, which tits into abearing formed for itat the center of permanent cross bar P. The permanent cross-bar I3 formsa firm support for the entire grate, and the bit'urcated brackets, whilemaintaining the grate in a horizontal plane during its oscillation,prevent the same from canting to one side and dumping the fuel and fireinto the ash-box. 'Ihe conical form ot the grate M' prevents clinker andashes from accumulating on the grate and in the iire-pot, as they willbe entirely removed from the grate and slide down into the ash-pit byshaking or oscillating the grate. This constitutes an irnportant featureot' my invention, sincel it obviates the necessity of removing theclinkers byopening three or more doors and picking them out with a hook,which, as is usual with other forms of grates, is an inconvenientoperation, and also gets the ashes over the stove and upon the oor ofthe room in which the stove is located.

By pressing down the handle N the center section, M', of the grate canbe readily tilted on its lugs m' for the purpose of dumping the deadcinders and ashes when it is desired to clean out the fire-pot.

What I claim is-I l. The stove-grate herein described, consisting of anoscillating upper conical section, M', and lower section, m, the conicalupper section, M', being provided with the handleN and with the lugs m',pivoted in bearings diametrically opposite each other in the lowersection, m, substantially as described.

2. The combination of the permanent supporting cross-bar, P, providedwith the vertical bifurcated brackets O, the oscillating In testimonywhereof I have hereunto set 1c cross-bar R, pivoted at the center ofsaid permy hand and seal in the presence of two submanent bar, the lowerconical grate-section, scribing witnesses.

m, rigidly connected to the opposite ends of 5 said oscillating cross-bar and bearing` upon cuARLEs H. GIBBs. [L s] saidbifurcated brackets,and the upper conical grate section, M', pivoted Within said Witnesses:lower conical gratesection, substantially as W. E. HOLGOMB, described.JAMES D. WOOD.
